the closed window (CW) starts. Then three valid watchdog triggers are shown, no effect
on the reset line and/or error pin is observed. With the missing watchdog trigger signal
the error signal turns low immediately where the reset is asserted after another delay of
half the closed window time.
Also shown in the figure are two typical failure modes, one pretrigger and one missing
signal. In both cases the error signal will go low immediately the failure is detected with
the reset following after the half closed window time.

Overtemperature Protection
At a chip temperature of more than 130° an error and temperature flag is set and can be
read through the SPI. The device is switched off if the device reaches the
overtemperature threshold of 170°C. The overtemperature shutdown has a hysteresis to
avoid thermal pumping.
2.11
Power Down Mode
The TLE 6361 G is started by a static high signal at the wake input or a high pulse with
a minimum of 50s duration at the Wake input (pin 34). Voltages in the range between
the turn on and turn off thresholds for a few 100s must be avoided!
By SPI command (“Sleep”-bit, D8, equals zero) all voltage regulators including the
switching regulator except the standby regulator can be turned off completely only if the
wake input is low. In the case the Wake input is permanently connected to battery the
device cannot be turned off by SPI command, it will always turn on again.
For stable “on” operation of the device the “Sleep”-bit, D8 has to be set to high at each
SPI cycle!
When powering the device again after power down the status of the SPI controlled
devices (e.g. trackers, watchdog etc.) depends on the output voltage on Q_LDO1. Did
the voltage at Q_LDO1 decrease below 3.3V the default status (given in the next section)
is set otherwise the last SPI command defines the status.
2.12
Serial Peripheral Interface
A standard 16bit SPI is available for control and diagnostics. It is capable to operate in a
daisy chain. It can be written or read by a 16 bit SPI interface as well as by an 8 bit SPI
interface.
The 16-bit control word (write bit assignment, see figure 8) is read in via the data input DI,
synchronous to the clock input CLK supplied by the C. The diagnosis word appears in
the same way synchronously at the data output DO (read bit assignment, see figure 9),
so with the first bit shifted on the DI line the first bit appears on the DO line.
The transmission cycle begins when the TLE 6361 G is selected by the “not chip select”
input CS (H to L). After the CS input returns from L to H, the word that has been read in
at the DI line becomes the new control word. The DO output switches to tristate status at
